T4.1 Performance Evaluation of the International Monitoring System
E-poster

The primary method the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO PrepCom) uses in monitoring for underground nuclear explosions is a seismic network of 50 primary stations and 120 auxiliary stations. Currently the primary network's detection capability has been calculated using theoretical methods. But now that a majority of the network has been...

T2.1 Characterization of Treaty-Relevant Events
E-poster

The classification of infrasound signals has important application value in the fields of nuclear test monitoring, earthquake and other natural disaster warning. However, traditional infrasound signals classification methods are difficult to effectively extract the significant features that quantify event differences. To address this issue, this paper proposes an end-to-end infrasound signal...

T1.1 The Atmosphere and its Dynamics
E-poster

During infrasound propagation in the atmosphere, shadow zones can be induced by the temperature and/or wind speed gradients, the ground surface or the source geometry. Although commonly used to simulate the atmospheric infrasound propagation at large scales and three-dimensional domains, acoustic rays method is not able to simulate the propagation where the geometrical approximation is not...

T3.5 Analysis of Seismic, Hydroacoustic and Infrasound Monitoring Data
E-poster

With the projected increase in world nuclear capacity comes the hurdle of spent nuclear fuel. Pyroprocessing is one method to process irradiated fuel by using high temperatures and electrochemical steps to separate radioactive components of interest. High temperatures, high radiation levels and equipment confined to a heavily shielded hot cell are a few of the challenges introduced regarding...

T1.4 Multidisciplinary Studies of the Earth’s Subsystems
E-poster

We performed a comprehensive analysis of the seismic activity in the Valley of Mexico using the records of the nearby seismic stations. We determine the focal mechanisms of earthquakes (M > 2.5) in the Mexico Basin from 2010 to 2024. Events were chosen with a high signal to noise ratio, i.e., raw P and S arrivals clear enough to be distinguished. Focal mechanisms were inverted using the ISOLA...

T1.2 The Solid Earth and its Structure
E-poster

The various microplates collided and resulted in Sulawesi Island. Compression stress became the main force at the beginning of tectonic episodes. Nowadays, two subductions still exist. However, it is still an open question whether those two subductions significantly contribute to seismic wave arrival times. The global 1-D and 3-D velocity models are used to identify the residual patterns in...

T3.5 Analysis of Seismic, Hydroacoustic and Infrasound Monitoring Data
E-poster

The Idaho National Laboratory (INL), located in Eastern Idaho in the United States, has a history of operating nuclear test reactors and is currently designated as a Reactor Innovation Center. The seismic monitoring network began as a single seismic station in 1973 and has grown to include over 100 instruments for the purpose of monitoring geophysical phenomena. As the network has evolved over...

T3.5 Analysis of Seismic, Hydroacoustic and Infrasound Monitoring Data
E-poster

Traditional moment tensor inversions are a common tool used to characterize events of interest for nonproliferation monitoring. Many inversions assume a known source time function and solve for the moment tensor of a seismic source. However, this requires a source time function to be assumed, which could result in inaccurate results if, for example, an explosion source time function is used...
